BUAL L. 10E LA MEER, 0F SAN EDEEGO, CLIFORM runt-minne nnvren To all 'whom t may concem Be it known that I, RUM. L. DE LA MATER, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented a Vnew and useful Fuel-Mixing Device,`of which the following is a specifica tion.

'.lhis invention relates to Avaporizers to be used in connection withvinternal combustion engines, the primary object ofthe vinvention being to thoroughly vaporize the incoming gas prior to its entrance to the intake manifold.

Another object of the invention is to provide a device of this character which will be automatic in its operation, and one wherein the valves will operate under the .slightest degree of suction.

A stillV further object of the invention is ,to .supply the charge with moisture to in- .'crease the volatility of the charge to insure the maximum amount of power with the minimum amount of fuel.

With the foregoing and other objects in vview Vwhich will appear as the description proceeds, the invention resides in the combi- ;nation and arrangement of parts and in the details of construction hereinafter de- `scribed andclaimed, it being understood Vlinvention as applied thereto.

Figure 2 is a detail view partly in section disclosing the needle valve that'controls the passage of fuel to the intake manion line reference character 5 designates an exhaust manifold of an internal combustion engine,

the reference character 6 designating an in- -take manifoldwhich is associated therewith. rlhe invention embodies a pluralit of heating tubes 7 which are supported within 6D the heads 8, the heads being circular in formation and of a diameter to closely fit within the exhaust manifold 5. Supported on the exhaust manifold 5 and in communication therewith is a housing 9 that has a 65 restricted portion 10 formed with a lian e 11 that is apertured to accommodate the securing bolts 12, whereby the device may be secured in position.

The upper end of the housing 9 is formed 70 with a recessed portion to vaccommodate the disk 13 that is formed with a plurality of spaced openings 14 and a central opening to accommodate the stationary` nozzle l5.'

The nozzlel supports a tubular'member 16 75 that is formed with a threaded portion-17 to be positioned on the supply pipe 18 that has connection with the gassupply as through the extension 19, the extension 20 providing means of communication between tacts with the disk 13 to hold the same, to- 85 gether with the nozzle Supported thereby in position. Positioned within the housing 9 is a movable needle valve supporting mem` ber 22, which has its lower end supporting the disk 23 which is formed with a plurality 90 of openings 24. The needle valve is indicated at 25, and extends upwardly from the head 26 that is supported within the central opening of the member 23.

Shoulders 27 are formed on the member 22 9e and provide a seat for one end of the coiled spring 28, the opposite end of the coiled spring, resting on the shoulder 29 formed at the lower end of the housing 9. The needle valve 25 moves into one end ofthe pipe 18 100 to control the passage of fluid through the pipe 18. From the foregoing it will be seen that when a vacuum is created within the housing 9, due to the pistons working Within their cylinders, the needle Vvalve 25 will 105 be moved downwardly admitting a quantity of fuel to the housing where the same is drawn over the tube 7 and into the intake' manifold 6, the movement of the needle valve 25 beingcontrolled hy the suction of the 110 engine to admit a quantity of fuel according to the speed of the engine.

Air enters the housing between the valve supporting member 22 and tliestationary nozzle 15, it being understood that the valve supporting member 22 is drawn downwardly against the tension of the spring 28 upon the movement of the pistons within their cylinders.

Communicating with the interior of the housing 9 is a pipe 30 which has communication with a suitable water su ply tank not shown for feeding .water'to t e housing 9. The valve seat 31 is formed in the pipe' 30 and is provided wit-h an opening to accommodate the needle valve 32 which is controlled by movement of the shaft 33 that carries' the usual butterfly valve 34 thereon.

An arm 34 has connection with the shaft 33 and is formed with an elongated opening 35 to accommodate the pin 36 carried by the needle valve, so that movement of the rod 33 to control the movement of the butterfly valve 34, will automatically admit quantities of water to the mixture.

An arm 37 extends into the housing 9 and has a tapered depending portion 38.lying directly over the restricted portion 18 of the housing, so that water entering the housing will flow outwardly over the arm and drop 'from the depending portion 38.

From the foregoing it Will be seen that as the butterfly valve is operated, to admit more fuel to the engine, the needle valve 25 is automatically drawn downwardly to admit a proportionate amount of fuel.

Having thus described the invention, what. isclaimed as new is 1. A fuel mixing device comprising a housing, a stationary nozzle supported wit-hin the upper end of the body portion, a movable valve supporting member operating within the housing, a coiled spring disposed within the housing and contacting with the valve supporting member for normally urging the valve supporting member to the -limit of its upward movement, a needle valve carried by the valve .support- 1,esa,aee a ing member and adapted to restrict the passage of fiuid through tbe'nozzle, and means disposed within the path oftravel of the fuel passing through the housing for delivering water to the fuel, and means lfor controlling the passage of fuel through the housing.

2. A fuel mixing device comprising a housing, a nozzle disposed at one end of the housing and adapted to feed liquid to the housing` a movable valve supporting member having an inclined upper surface positioned within the housing and adapted to cooperate with the nozzle for admitting air to the housing, a needle valve within the housmg and supported by the valve supporting member, Said needle valve adapted to control the passage of fuel through the nozzle, an arm extending into the housing at a point in spaced relation with the needle valve, said arm having a depending por- Y tion to allow water to pass therefrom to the housing drop by drop, said arm lying in the path of. travel of the fuel through the housing.

3. A fuel mixing device comprising a housing, a nozzle supported at one end of the housing. and adapted to `feed fuel to the housing, a spring pressed valve supporting member movable through the housing, a needle valve carried by the valve supporting member to control the passage of fuel through the housing, means for delivering water drop by drop to the housing, said water feeding means lying in the path of travel of fuel passing to the housing, and means for controlling the passage of fuel from the housing.

- In testimony that I claim the'foregoing as my own, I have heretoaifixed my signature in the presence of two witnesses.
